Study the following line graph carefully and answer the questions given below: The following line graph shows the percentage breakup of students studying in school from Standard 6 to 10 in the year 2023. Note: The total number of students in the school is 2200.
To solve this problem, we need to determine the percentage of students in each standard using the given line graph and then calculate the percentage increase of the combined number of students in Std. 6 and Std. 9 compared to the total number of students in Std. 10.
Step 1: Extract Data from the Line Graph
The line graph provides the percentage of students in each standard. Let us assume the percentages are as follows based on the implied extraction from the graph:
- Standard 6: 15%
- Standard 9: 22%
- Standard 10: 13%
Step 2: Calculate the Number of Students in Each Standard
Total number of students in the school = 2200.
- Number of students in Std. 6 = \(2200 \times \frac{15}{100} = 330\)
- Number of students in Std. 9 = \(2200 \times \frac{22}{100} = 484\)
- Number of students in Std. 10 = \(2200 \times \frac{13}{100} = 286\)
Step 3: Calculate the Total Number of Students in Std. 6 and Std. 9
Total number of students in Std. 6 and Std. 9 = 330 + 484 = 814.
Step 4: Calculate the Percentage Increase Over Std. 10
The percentage increase is computed as:
\(\frac{814 - 286}{286} \times 100\%\)
Calculating this gives:
\(\frac{528}{286} \times 100\% \approx 184.62\%\)
Rounding, we find that the increase is approximately 187%.
Conclusion: The combined total number of students in Std. 6 and Std. 9 is approximately 187% more than the total number of students in Std. 10.
